Blackhawk lies at the mouth of Chase Gulch near Central City in Gilpin County, Colorado. A railroad track forks in the foreground with one portion leading to the Polar Star Mill at right. The Empire Mill stands in the midground, and the Boiler Room and Machine Shop of the Fifty Gold Mines is in the right background with four smokestacks protruding from its roof. Additional smokestacks from other buildings jut into the skyline.
